Khrono is a digital watch, timer and countdown for the
KDE desktop, distributed under the GNU Public
License. It's a nice utility with many
features found on regular timers: lap function, reset, start/stop, audio alarm
for countdown. It also supports some customization: you can select colour themes
and change the audio file played as the alarm.
Khrono docks on your Kpanel too, and is fully controllable with the mouse through
its dock icon. This allows to control Khrono while interacting with another
program through the keyboard. As an example, I use Khrono as a timer for my
sequencer: I begin the playback of my song on the sequencer, pressing the space
bar, and in the same time, I start Khrono's timer with a mouse click on the Kpanel.
